Samples from Prior Testing. Reliable results depend on many factors; Practice D provides a means of evaluating some of those factors. However, the applicable sections above should be used in applying this standard. Hand Sieve Shaking Procedure. The procedure selected will depend on the type of sample, the maximum particle-size in the sample, the range of particle sizes, the initial conditions of the material, the plasticity of the material, the efficiency, and the need for other testing on the sample.

In addition, they are representative of the significant digits that generally should be astmm.

ASTM D Standard

Composite Sieving, Single Separation. However, the applicable sections above should be used axtm applying this standard. The mass of particles retained on each sieve will be determined. Composite Sieving, Mass of Specimen. Furthermore, if the maximum particle size is greater than the 4.

Finally, if the maximum particle size is equal to or greater than The quality of the result produced by these test methods is dependent on the competence of the personnel performing it, and 6d913 suitability of the equipment and facilities used.

For cases of disputes, Method A is the referee method. Large Mechanical Sieve Shaker. Proceed to Checkout Continue Shopping.

If the d9613 is revised or amended, you will be notified by email. It is beyond the scope of these test methods to consider significant xstm used in analysis methods for engineering design.

Furthermore, if the maximum particle size is greater than 4. Splitter or Riffle Box optional. For a single separation two portionsthe coarser portion is sieved in its entirety, while the finer portion is split into a smaller subspecimen for sieving.

The results will produce a tabulation of sieve sizes versus percent passing that can be graphically presented as a gradation curve a plot of the percent passing versus the log of the particle size in mm. These data are combined to determine the particle-size distribution gradation. This method must be used when performing composite sieving. Using an Ultrasonic Water Bath.

Definitions of Terms Specific to This Standard. Dispersing and Washing Subspecimen. This test method is used to separate particles into size ranges and to determine quantitatively the mass of particles in each range. Selection of Sieving Procedure.

ASTM D6913

Typical examples of these soils are some residual soils, most weathered shales and some weakly cemented soils such as hardpan, caliche or coquina. The procedure selected will depend on the type of sample, the maximum particle-size in the sample, the range of particle sizes, the initial conditions of the material, the plasticity of the material, the efficiency, and the need for other testing on the sample.

The procedures used do not consider material variation, purpose for obtaining the data, special purpose studies, or any considerations for the user’s objectives; and it is common practice to increase or reduce significant digits of reported data to be commensurate with these considerations.

This test method is used to determine the particle-size distribution gradation of a soil sample. Depending on the design considerations, a specialized gradation-testing program could be performed.

Subspecimen from Finer Portion. Standards Subsctiption may be the perfect solution. For special conditions see Dispersing and Washing 2 nd Coarser Portion.

Request Quote Client Login. Dry Sieving Coarser Portion. However, the use of balances or scales recording pounds of mass lbm shall not be regarded as nonconformance with this standard.

These data are combined to determine the particle-size distribution gradation. Furthermore, if the maximum particle size is greater than 4.

Finally, if the maximum particle size is equal to or greater than Please first verify your email before subscribing to alerts. This standard is not included in any packages. This method must be used when performing composite sieving. D913 view current version of standard.

However, the specimen may contain a wide range of particle sizes and may require separating the soil into two, or three size ranges for more efficient sieving, using one or two designated separating sieve s.

These results are mathematically combined. The methods differ in the significant digits recorded and the size of the specimen mass required. This method is only applicable for single sieve-set sieving and when the maximum particle size is equal to or less than the No. The material to be sieved will be placed on the coarsest sieve size of each sieve set and mechanically shaken.

Dispersing and Washing 2 nd Subspecimen. Specimen Procurement and Processing Requirements. The procedure may be specified by the requesting authority; otherwise the guidance given in Section 10 shall be followed.
